To all whom. it may concern:

Be it known that I, WILLIAM ScHwANnAUssnR, a. citizen oi the United States` residing at- New York city, county ol Kings, and State of New York. have in- .'ented certain newand useful Improvements in Sur.

face (londensers, fully described and represented in the following specification anti the accompanying drawings, forming a part oi the same.

This invention relates to that class of condenser sysl() tems employing surface condensers from which the air 11nd nn'eondensed vapors are withdrawn separately from the water of condensation by an air or vacuum pump` the especial object' of the invention being to provide an improved construction of surface condenser l5 for efiieiently separating the' air and uncondensed vapor from the water and cooling them for delivery by the air or vacuum pump.

In constructions 4embodying the present invention, the air and uneondensed vapor is dra-wn off trom the lower part otl the condenser through an air cooler located in the bottom of the condenser and cooled by the condensing water, so that the lair is efficiently removed and cooled, and the combined condenser and air cooler' is simple and cheap in construction and convenient in use.

drawings forming a part of thisispeciiication. as applied in two forms of surface condensers, embodying the in- Vention-.in the preferrediorms, and these constructions will now be described in detail, and the features forming 'the invention then specifically pointed out in the claims.

In the drawings-Figure l. -is n vertical section of an ordinary cylindrical surface condenser modified in accordance with my invention. Fig. 2 is a vertical centrai cross section ol the same. Fig, 3 is a horizontal section above the uit-'cooler with the top plate ot the air cooler partly broken away. Figs. 4,5ai1dt are repsectivelyside and end elevationsand plan view of a steam turbine condenser embodying the invention. Fig. 7 isa 40 vertical section on line 7 of Fig. (i, on an enlarged scale.

Fig. 8 is a horizontal section on the line 8 of Fig. 7.

Fig. 9 is a vertical cross section on the line 9 of Figs. 7 and 8.

Referring now'to the construction shownin ligs. l to 3, A is a horizontal condenser having the inlet B at theV l top for the exhaust steam and the usual well C at the bottom for the water ol' condensation. this well being connected by pipo l0 to the discharge pump. The coitdenserhas the. usual tubes D for the circulating or condensing water, .which water enters the inlet chamber` Eet' one end of the condenser, passes through the lower tubes and the chamber F at the opposite end of the The invention is illustrated in the accompanying condenser, then through the upper tubes to the outlet chamber G. i

All the parts thus far described are well-known and may be of any common or suitable construction.

Referring now to the parts embodying the invention, an air cooler is formed -in the bottom of the condenser A by plate l1 shown as resting upon shoulders on the opposite sides of the condensa-and covering a space between it and the bottom of the condenser through which pass tubes l2 which may be similar to the condenser tubes D, and which connect the chambers E, I", so that some of the condensing water passes through these tubes andcools the air in the air cooler below the plate 1l. In the bottom of the condenser is anarrow trough 13 extending longitudinally ofthe central por` tion of the condenser bottoni, and thistrough receives the water of condensation from the condenser throughL the openings l in the plate 1l and it passes fromI the 70 trough 13 to the well C through a central'opening in the f bottom of the trough above the well. The air from the condenser passes to the air cooler through the trough 13 by openings 2 in the plate ll and openings 3 in the upper portion of the side walls of the trough, The openings 2 are provided with upwardly extending flanges, as shown, so as to prevent the water flowing through these openings, and the side openings 3 of the trough are raised sufficiently above the bottom of the trough to permit the air to pass out into the air cooler 8O above the water of condensation flowing to the Well C.

The air is drawn off from the air cooler below the plate l1 through outlet pipe II to which the air or suction pump is connected, the air being efliciently scpzb rated from the water and cooled before leaving the 8 5 condenser casing.

The construction shown in Figs. l to 9 is adapted foruse with the condenser forming a support for the steam turbine, which is mounted upon and exhausts-directly to the condenser, the condenser being formed in-two 9() longitudinal sections, or having a central chamber, to provide a central support for the turbine and accommodate the turbine shaft.A In this construction I is the condenser casing provided with the tubes K and having the inlet chamber L and outlet chamber M in one section, the circulating chambers il, and the passages O connecting the upper andlower, circulating charnbers at one end otthe condenser. The discharge water is drawn olf iromboth sections oi the condenser by the discharge pipe P and the air und uncondensed vapors are drawn off centrally from the sides ofthe two condenser sections by pipes Q connected tothe air or vacuum pump.

Referring now to the air cooler construction, the

between tie streams of Water owing from the plates 14 I where the anges are cut away. The air cooler tubes 15 are within the space between the plates 14 and the bottoni wall 16 oi the condenser, this bottom wall 16 being inclined as shown so to direct the water of condensation downward and to the discharge pipes' P.

The air cooler acts as a supplementary' condenser, and any water condensed from the vapor by the ltubes l5 will flow down the inclined bottom ,16 and thus be delivered with the Water that is condensed by the tubes K and which flows over the edge oi the plates-14.

The air passes through the cooler above the water and outward through passages 5 to the air pipes Q and is drawn off by the air or suction pump, being eiiiciently separated from the Water of condensation and cooled before leaving the condenser casing.

It will be understood that the invention is not to be limited 'to the special types of surface condenser shown, nor to the exact form or arrangement of devices for separating and cooling the air7 but that the invention may be applied to surface condensers of other forms than those shown, and many modifications may be made in the devices for carrying out the invention.

WhatI claim is:-

1. li surface condenser having an air cooler in the lower part of the condenser below the condensing surfaces and provided with passages for the condensing water to cool the air cooler and for the air to pass from the condenser separately from the water of condensation.

'.2. A surface condenser having a bottom space separated from the condensing space bj' ahorizontal partition, constructed to permit the passage of the air and water of condensation from the condensing space to the space below said partition. separate deliveries for said air and water ot' condensation, and tubes through which the condensingr water passes within said space for cooling the air and condensing vapor therein ou its way to its delivery.

3. A surface condenser having u bottom plate over which the water of condensation passes t0 its delivery, a partition above said plate with space between the partition and bottoni plate providing,r for the passage of airad water oi' condensation from the condenser', tubes below the partition through which the condensing water passes to form an air cooler, and an air delivery to which the air passes from said cooler.

4. 'lhe combination with the condenser casing," of plate 11 formin.;r a partition to separate the lower portion ot' the space within the casing from the condensing space, tribes i2 in the bottom space through which the condensing water passes to form an air cooler, trough 13 below the plate il, said plate and trough having openings for the passage oi' water of condensation from the condensing spare to the water delivery and openings for the passage olair from the condensing space through said trough above the water oi' condensation to the air cooler, and an air delivery from the air cooler.

ln testimony whereof, l have hereunto set my hand, in the presence of two subscribing; witnesses.
